Chromosomes tell tale of patient's risk for new, future cancer

Hodgkin's disease survivors who have greater genetic instability in their white blood cells are two-and-a-half times more likely to develop another type of cancer, researchers from The University of Texas M. D.Anderson Cancer Center report at the American Association for Cancer Research annual meeting in Los Angeles April 14-18.
